您可以使用 pcs 命令修改 corosync.conf 文件中的参数。
以下命令修改 corosync.conf 文件中的参数。
pcs cluster config update [transport pass:quotes[transport options]] [compression pass:quotes[compression options]] [crypto pass:quotes[crypto options]] [totem pass:quotes[totem options]] [--corosync_conf pass:quotes[path]]
pcs cluster config update [transport pass:quotes[transport options]] [compression pass:quotes[compression options]] [crypto pass:quotes[crypto options]] [totem pass:quotes[totem options]] [--corosync_conf pass:quotes[path]]
以下示例命令会更新 knet_pmtud_interval 传输值，以及 token 和 join 令牌值。
pcs cluster config update transport knet_pmtud_interval=35 totem token=10000 join=100
# pcs cluster config update transport knet_pmtud_interval=35 totem token=10000 join=100
